I may have got this wrong but, as of today, I am still struggling trying to have the user know that my standalone is running and not locked in limbo.
Despite what Apple says ( that on mobile the user should never have to wait), there is a need, on PC and mobile, to have a "wait" spinner in LiveCode that is not disturbed by other scripts running.
The Standalone may be checking internet, change the language, load files or do other long operations that both on a computer and on a phone require even 10 seconds.

I tried widget, gif, send in time, Spinner store, etc. but to no avail. They work in a jerky way, if the standalone is doing something else.

I am tempted on creating a small spinner App, to be loaded inside the standalone and launched and repositioned by this, but it will take a good deal of time and I am not sure if it will work.
Anyway, I think that this is an important problem and, if possible, should be addressed by the LC team.
Unless I am missing something.

mmmh...your answer somehow imply that wait time is a problem of mine, not everybody's. How that's possible?
Anyway, I will make a try, but it may slow to a croll other parallel script. Or not?
Are you saying that this two will share ticks on a PC/mobile?
